The Humidity Indoors

The humidity inside your home can affect your windows being foggy. If the air inside the room is dry, your windows will have a higher chance of getting foggy, especially if you've been running AC or a dehydrator. It is one of the most common causes of foggy windows.
If this happens to you, you can try and use a humidifier for your whole house or observe if your AC is too strong and try increasing its temperature a bit.

The Humidity Outside

The moisture outside can also affect your windows getting foggy. If the outside is humid, the condensation will be getting on the window. It is something that happens, especially if you live in a place where it rains a lot.
If this is happening to you, there are things you can do to decrease its effects. One of these is to adjust your AC's temperature to get the humidity below 70%. Another thing that works well for this problem is installing an air conditioner.

The Location of Your Windows inside the House

Windows near or facing North and East will be more prone to moisture and humidity, especially if it's humid outside. It is because the sun rises from the east and sets in the west. It means that your windows face the north during sunrise and the south during sunset, which is when moisture and humidity gather.
If this is happening to you and you can't move your window (and there's no other option), you can increase the temperature in your house, decrease humidity and close your curtains.

Worn out Windows Caulk

The rubber sealant of the windows is worn out or has deteriorated. In such a state, it can allow moisture to get through and cause fogging. It is the case in older homes; the rubber seal of the windows has already lost its elasticity and flexibility.
Sometimes, you can replace it with another piece of rubber, but it may not always be possible, and you'll need to replace the whole window.

Not Keeping Your Windows Clean

If you haven't cleaned your windows in a while, the dirt will get on the surface, blocking the light. It's pretty easy to clean them, though. You can do it by either spraying glass cleaner or wiping them with a microfiber cloth.
If this doesn't solve your problem, there are more serious reasons why your windows are permanently foggy. They are usually caused by more serious issues within the house that you might not have thought of before.

Broken or Leaking Gutters

A leak in your gutters may allow water to get in and make its way to your windows, increasing their humidity and moisture level. It will cause them to get foggy and hinder visibility. It doesn't only happen in the summer. It can also get more severe during wintertime when you get more snow and ice accumulation.
